Preamp Output Impedance for my Amp


Folks,

I have a powermaster 2000 amplifier with the specs located here:

http://www.alphadigitaltech.com/pdf_files/PowerMaster%20specs.pdf

(It appears that input impedance is "25K + 25K"

What output impedance would be ideal for a preamp sending a signal to this amplifier? Also, what is the math required to find the answer?

Thanks for your help!

thanks, folks. Saw a number of posts to the fact, and started to get worried as I continue the search for a preamp. Y'all have been great help in my search!
